Figure 6.

Seed-PLS results for the left caudate nucleus seed that illustrate regions of the brain that also showed elevated activity during the CHAIR and WALK conditions. The coactivity pattern from the caudate seed found in young monkeys is reflected in the magenta regions. No significant pattern was found in older monkeys from this seed. Seed-related correlation plots reveal a significant pattern in young monkeys, but not in aged monkeys (a). Patterns of FDG metabolism in horizontal slice by slice 2D sections (b) and reconstructed 3D metabolism maps (c) that illustrate the functional connectivity of the caudate seed in the young animals.
